1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. What is the priority for a client with dehydration?

• A. Administer antiemetics to prevent nausea
• B. Monitor electrolyte levels to prevent imbalances
• C. Administer oral rehydration solutions
• D. Administer intravenous fluids

Correct answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.

3. What is the most appropriate next step when a client with an NG tube attached to low suctioning becomes nauseated, and the nurse observes a decrease in the flow of gastric secretions?

• A. Increase the suction pressure
• B. Irrigate the NG tube with sterile water
• C. Turn the client on their side
• D. Replace the NG tube with a new one

Correct answer: B

Rationale: The correct answer is to irrigate the NG tube with sterile water. When a client with an NG tube attached to low suctioning becomes nauseated and there is a decrease in the flow of gastric secretions, it indicates a possible blockage in the tube. Irrigating the tube with sterile water can help clear the blockage, allowing for proper suctioning and relieving the client's nausea. Increasing the suction pressure (Choice A) can further worsen the issue by potentially causing harm to the client. Turning the client on their side (Choice C) may not address the underlying problem of tube blockage. Replacing the NG tube with a new one (Choice D) should only be considered if other interventions, like irrigation, fail to clear the blockage.

4. A client is receiving furosemide. Which of the following laboratory values should the nurse monitor?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.

5. A client with dementia is at risk of falling. What is the best intervention to prevent injury?

• A. Place the client in a room close to the nurses' station
• B. Use a bed exit alarm
• C. Encourage family members to stay with the client at all times
• D. Raise all four side rails

Correct answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.
